COPD is the fourth leading cause of death in the United States and is a serious respiratory illness characterized by years of progressively debilitating breathlessness, high prevalence of associated depression and anxiety, frequent hospitalizations, and diminished well-being. Despite the potential to confer significant quality-of-life benefits for patients and their care partners and to improve end-of-life (EOL) care, specialist palliative care is rarely implemented in COPD, and when initiated, it often occurs only at the very EOL. ⋯ This review solidifies that palliative care is much more than hospice and EOL care and demonstrates that early palliative care is appropriate at any point during the COPD trajectory. We emphasize that palliative care should be integrated long before the EOL to provide comprehensive support for patients and their care partners and to prepare them better for the EOL.

Randomized Controlled Trial
Effects of CPAP on Metabolic Syndrome in Patients With OSA: A Randomized Trial.
OSA is associated with metabolic syndrome (MS), but it is unclear whether OSA treatment with CPAP can revert MS. ⋯ Despite the higher rate of MS reversibility after CPAP therapy as compared with placebo, most patients retained this diagnosis. The lack of significant or relevant effects on adiposity biomarkers and depots supports the modest role of OSA in modulating MS.

Improved treatments for cystic fibrosis (CF)-related lung disease have resulted in increased longevity, but also increased prevalence and severity of extrapulmonary manifestations of CF, treatment-related complications, age-related conditions, and psychosocial effects of longstanding chronic disease. Likewise, the recognition of mild CF phenotypes has changed the landscape of CF disease. This review outlines our current understanding of the common extrapulmonary complications of CF, as well as the changing landscape and future directions of the extrapulmonary complications experienced by patients with CF.

Central sleep apnea (CSA) frequently coexists with heart failure and atrial fibrillation and contributes to cardiovascular disease progression and mortality. A transvenous phrenic nerve stimulation (TPNS) system has been approved for the first time by the Food and Drug Administration for the treatment of CSA. This system, remedē System (Zoll Medical, Inc.), is implanted during a minimally invasive outpatient procedure and has shown a favorable safety and efficacy profile. ⋯ In this article, we review the background and efficacy data of TPNS and briefly address relevant aspects of the clinical activities involved in a TPNS program. The article presents the status of coverage and reimbursement for this novel therapy. We also discuss the current approach to obtaining reimbursement from third-party payors during this transitional period of evaluation by Medicare and other insurers.

Multicenter Study
Identification of Sputum Biomarkers Predictive of Pulmonary Exacerbations in Chronic Obstructive Pulmonary Disease.
Improved understanding of the pathways associated with airway pathophysiologic features in COPD will identify new predictive biomarkers and novel therapeutic targets. ⋯ Biomarker evaluation implicated pathways involved in mucus hydration, adenosine metabolism, methionine salvage, and oxidative stress in COPD airway pathophysiologic characteristics. Therapies that target these pathways may be of benefit in COPD, and a simple model adding sputum-soluble phase biomarkers improves prediction of pulmonary exacerbations.
